Research results on innovative equipment systems for production of silage as animal feed by five Hanoi students has been included in the Vietnam Yellow Book of Innovation 2021.

The five students received first prize in the 16th National Youth and Children’s Innovation Contest 2020.

The team of five students from Hanoi includes Le Thi Thanh Huyen, Nguyen Quynh Huong Ly (Cau Giay High School); Le Minh Hieu (Pascal Secondary School); Trinh Ha Phuong (Van Dien Secondary School) and Nguyen Huong Minh Trang (Giang Vo Secondary School).

In an interview with VietNamNet, Nguyen Quynh Huong Ly, a member of the group, explained that the group has been researching domestic and foreign documents, collecting and consulting experts to implement the project, which is called ‘Systematic model equipment for cutting/chopping, drying grass/maize, using solar energy and bagging silage for animal feed’. This stems from the actual demand for silage for livestock and development of mulato grass fields in Binh Thuan, Ha Nam, Ba Vi (Hanoi) and Moc Chau (Son La).

A visual working model was created describing the operation of a closed equipment system, and the processing of cattle silage, including cutting – mincing (3-6 mm), drying grass/corn using solar energy (reaching 65-70 percent moisture content), spraying probiotics, and bagging silage.

“To help the growth of Vietnam’s livestock industry, our hope is to put it into action,” Huong Ly said.

Because her grandparents lived in Thanh Hoa and had a farm and animals, Huong Ly was exposed to the realities of rural life when she visited her hometown. The team consists of five students from four separate school, but they all have the same goal in mind.

As a first step in this project, three components must be assembled securely: hash cutters, a drying house powered by solar energy, and a bagging machine.

The electrical wires of the control cabinet are connected to the fan motor, the chopper, the conveyor motor, and the heat-adding fan motor; and the press cylinder is connected to a hydraulic/pneumatic source (the conveyor and the presser cylinder work in unison to a programmed rhythm when the material is full).

If the moisture content of the material is more than 70%, the operator uses a fan, seals the door securely, and conducts the drying process to the appropriate humidity.

To begin the next phase, the drying house door is opened, the conveyor is turned on, and the probiotic nozzle is inserted into the press chamber. The conveyor will stop, and the presser of the moving cylinder compresses the material tightly into the PP/PE bag, which is then blown out through the holes in the press up. A rubber band is needed to secure the mouth of the presser as it rises after a hard press. Using the next set of bags, the identical procedure will be followed. In around 21 days, the silage product may be fed to animals without any further processing.

New endeavor

This research by the group of young students is described in the Vietnam Yellow Book of Innovation 2021 as an entirely new topic.  Drying raw materials for silage in a glass cage instead of outside is convenient, clean, and saves surface space while also saving energy by utilizing solar radiation and the glass cage effect. Silage-making machines that use air or hydraulic cylinders and pressers to compress grass and corn into silage bags are new and transportable.

Moreover, cutting, mincing, drying and spraying probiotics on the same machine provides a closed manufacturing process toward industrial production, which is a major innovation in this field of research. The drying house powered by solar energy may also receive raw materials of grass and maize that have been gathered and cut by specialized machinery in the field. The chopper isn’t required to function at that point, illustrating the system’s mobility.

The Vietnam Yellow Book of Innovation 2021 features research of the group of students.

Ventilation doors can be opened at the bottom edge of the mesh floor so that the natural drying process can be carried out and the product is not harmed by being stacked up when there is no sunlight (at night, or during rain or power outages). There is a wide range of materials readily accessible on the domestic market, and the process of creating it is straightforward.

Closed, dust-free setting of this research conducted by the group also helps minimize environmental impact.  Combining radiation and the glass cage effect for drying, lowering the moisture content of raw materials for silage, without exposure to the sun, is simple, clean and saves time and space. Organic, clean, and quality-controlled livestock products are the future of agricultural sphere.

It is also possible to decrease heavy labor by shifting livestock production towards industrial production, maximizing productivity, cutting costs, and using livestock machinery to guarantee adequate feed for cattle.

Vietnamese agriculture, according to Huong Ly, is a matter of concern today. Preservation of animal feed is required to both improve quality and provide assistance for farmers.

Huong Ly is now a student at Hanoi Law University as a freshman. The remaining four members, Le Thi Thanh Huyen, Le Minh Hieu, Trinh Ha Phuong, and Nguyen Huong Minh Trang, are still in middle and high school.

After winning the top place in the 16th National Youth and Children’s Innovation Contest conducted by the Union of Science and Technology Associations and Vietnam Engineering in 2020, the research of the group of Hanoi students’ was featured in the Vietnam Yellow Book of Innovation 2021.

Ho Chi Minh City’s ward to set up task force against uncontrolled waste disposal

Published

on

The administration of a ward in Ho Chi Minh City, southern Vietnam, will establish a dedicated team in charge of detecting and handling cases of random garbage disposal to protect the living environment for local residents.

The An Phu Dong Ward will install cameras and set up a specialized team to monitor and check local riverbanks and canals to detect, prevent and handle cases of illegal dumping, Le Phan Quang Tien, deputy chairman of the ward People’s Committee, in District 12, told Tien Phong (Youth) newspaper.

Such a task force is necessary as people who sneakily dispose of waste often commit their wrong act at night or early morning, when everybody is in a deep sleep, Tien said.

“In order to eliminate improper garbage disposal, we are implementing flexible and practical solutions to tighten control over environmental sanitation, including enhancing public awareness of environmental protection,” the official added. 

He emphasized that the ward will adopt a mechanism to mobilize the role of people and communities to detect and denounce acts of littering in public places.

At the same time, authorities will reward individuals and units who promptly identify and report violators, Tien stated.

Currently, there have been a lot of rubbish heaps alongside the banks of the Vam Thuat River and on roads, with rats and cockroaches running in and out, Tien Phong (Youth) reporters recorded on the site.

Except for small volumes of domestic waste, such garbage there is mainly industrial and construction waste, including broken pieces of metal, glass and electronic appliances.  

Many people even burned metal waste to get copper wires, causing smoke and dust pollution and posing risks of fire or explosion, locals complained.

“Most of the refuse here has been brought in by tricycles hired by people living in other localities,” Son, a local public utility staff, said, adding that such tricycles often came late at night to dump waste stealthily. 

Son emphasized that there are not enough forces to handle such violations.

Thao, a woman who owns a beverage shop in the riverbank area, said there were times when waste occupied roadways and travelers had to avoid them while going by.

“Recently, some residents had to spend millions of dong (VND1 million = US$41) hiring people to clean up trash heaps that are ‘as high as mountains,’ Thao said.  

She noted that authorities have caught and penalized many people who randomly disposed of waste here but the situation has yet to be improved.

Thao said locals will help local administration to drive back the situation by detecting and reporting those who commit such acts, but heavy fines should be imposed to deter wrongdoers.
